Abstract
Photometric reductions of the spectrograms obtained during the third flight of the Soviet Stratopsheric Solar Station are discussed. A comparison of photometric scans in Hα and its far wings near to the continuum leads to the conclusion that chromospheric ‘mottles’ are at least several times broader than photospheric granules. The optimum size of mottles is about 0″.8–1″.1. The Hα profiles of mottles are practically the same as those obtained from the ground observations. The broadening of mottles is considered as an effect of expansion of magnetic arcs growing up to chromospheric levels.
